I am not exactly sure, why Vim doesn't highlight the second comment. But
here is a way to make what you want. Create a file
~/.vim/after/syntax/tex.vim
and insert there:

syn keyword globalTodo contained XXX TODO NB FIXME WARN
syn cluster texCommentGroup add=globalTodo
hi link globalTodo Todo

That should be it. By modifying the texCommentGroup cluster, you can add
more syntax items to all comment sections in your file.
